How can the use of <base> in PHP help address path-related problems when including files from different directories?

When including files from different directories in PHP, path-related problems can arise due to the differences in file paths. Using the <base> HTML tag in PHP can help address this issue by allowing you to set a base URL for all relative paths, ensuring that included files are referenced correctly regardless of the directory they are in.

&lt;?php
echo &#039;&lt;base href=&quot;http://www.example.com/&quot;&gt;&#039;;
include &#039;folder/file.php&#039;;
?&gt;
